Description

 Thinkre™ reinforced proton exchange membrane is produced by using PFSA resins with appropriate molecular weight and ion exchange capacity through tape casting process. The membrane we produce has uniform thickness and is widely used in electrolytic chlorine dioxide generator,copper recovery by etching solution, gold salt preparation, amino acid refining, caustic soda preparation, electrodialysis, water treatment and other electrolytic industries.

The Proton exchange membranes for electroplating we produce have excellent conductivity and ion selectivity, which improves the efficiency and quality of the electrolysis and electroplating processes, thereby ensuring the quality of the final product. Using advanced materials and manufacturing technologies, the Proton exchange membranes for electroplating we produce have excellent mechanical and chemical stability, can withstand harsh working conditions, and extend service life.

   Measurements taken with membrane conditioned to 23°C, 50% RH for 24h.

   A base titration procedure by using the caustic soda measures the equivalents of sulfonic acid in the membrane, thus calculating the acid capacity or equivalent weight of the membrane.
